Currently, I saw video tutorial, like SQL queries , styling code ,tutor simply pasting code where ever required and telling you can download this from resources.

Ex: https://www.youtube.com/watch?v=_FEWkyO7oPY @time 4:50 you can see , how he is pasting. From where he is pasting actually. That source I need so that I can also copy the code. In other lesson SQL queries have been pasted.
